MACHINE FOR FINISHING PLUSH.

SPECIFICATION forming part of Letters Patent N o. `415,009, datedNovember 12, 1889.

Application led March 6, 1889.

To all whom t may concern:

Be it known that I, PETER VAN DEN ESCH, of Steinway, in the county ofKings and State of New York, a citizen of the Empire of Germany,haveinvented certain lnew and useful Improvements in Machines forFinishing Plush, of which the following is a specification.

This invention relates to an ilnproved machine for finishing plush, sothat the same receives a glossy and linished appearance over the entiresurface of the raised nap; and the invention consists of a machine forfinishing plush, composed of a number of driving and guiding rollerssupported on a suitable frame, a rotary beating device for the plush atone end of the frame, an atomizer for applying the size by which thegloss is imparted to plush, said atomizer being located adjacent to saidbeating device, a number of brushrolls and intermediatesupporting-rollers, a guide-drum, and a heating device below said drumfor drying the plush and imparting luster to the same, said drum aroundwhich the plush passes being readily lifted by ymeans of a hand-leverarrangement whenever a seam passes between the drum and heating device.

The invention consists, further, of certain details in the constructionof the machine, which will be fully described, and finally pointed outin the claims.

In the accompanying drawings, Figure l is a side elevation of myimproved machine for finishing plush. Figs. 2, 3, and 4t arerespectively a partial elevation, a partial horizontal section, and avertical transverse section of the atomizer, by which the size isapplied to the nap of the plush. Fig. 5 is a side elevation of theheating device for drying the plush. Fig. 6 is an end elevation of thesame, and Fig. 7 is a vertical longitudinal section of the heatingdevice on line y y of Fig. 6 on aflarger scale. Fig. 8 is a transversesection, partly in elevation, on line x x of Fig. 5, on a larger scale.

Similar letters of reference indicate corresponding parts. i

' Referring to the drawings, A represents the supporting-frame ofmyimproved machine for finishing plush, which frame is provided at oneend with a number of tension-rods cay Serial No. 302,154. (No model.)

and a guide-roller l), over which the fabric is passed and from whichthe same is conducted'4 in a longitudinal direction with the napdownward over a number of rotary brushrolls C and under intermediatesupportingrolls O', which latter are supported in bearings of standardsC2 on a plane above the brush-rollers.

A rotary beater D is disposed at one end `of the machine over the. pathof the fabric; As shown, this rotary beater consists of spiderframes d,supported on a shaft d5, and rods d, supported at their opposite ends insaid spiderframes. As the beater revolves, the rods d come in contactsuccessively with the back of the plush and impart a quick succession ofblows thereto, serving as whips to beat out the dust therein contained.These rodsV or whips dare preferably j ournaled in the spiderframes sothat they will rotate axially when in contact with the plush, wherebyfriction is avoided. The shaft d5 of the beater-frame D is supported inbearings in horizontal brackets d', which are verticallyT adjustable bymeans of screws d2 on vertical guide-standards d3 of the main frame A,as shown clearly in Fig. l. By adjusting the beater-frame lower orhigher in its supporting-standards the beaters or whips exert a greateror less effect on the plush fabric, so as to beat the same more or. lessviolently, according to the size of the nap and quantity of dustcontained in the same. 9

Adjoining the rotary beater-frame D and between the same and the firstbrush-roll C is arranged an atomizing apparatus E, which is clearlyshown in detail in Figs. 2, 3, and 4. The atomizing apparatus E servesthe purpose of supplying a suitable size in finely-divided state intothe nap of the plush in such a manner that all the fibers of the napreceive some of the size. For this purpose the size is placed in areservoir E', from which it is conducted by a pipe e, provided with astopcock e', into a horizontalcylindrical receptacle E2, which isprovided at one end with an ordinary water-gage W, for indicating thequantity of size in the same. From the cylindrical receptacle E2 thesize passes through a horizontal channel c4 below'the receptacle E2 intoa second smaller supply-cylinder E3, from IOC) pipes with taperingnozzles e2 in upward direction, as shown clearly in Eig. 4. Between thelarger and smaller cylindrical receptacles E2 E3 is arranged alongitudinal air-tube E, which communicates at both ends by pipes e:3with a suitable source of supply of compressed air. The air-tube E4 andthe sizereceptacle E3 are divided midway by transverse partitions E13into two halves, and there is a channel et at each end of the atomizer,so that each half can be worked independently of or jointly with theother half.

The atomizing apparatus, as well as the beaters and the brush andsupporting rolls, are of such a width that simultaneollsly two widths ofplush can be passed over the finishing-machine. In case one piece onlyis to be linished the air and size supply pipes of the other half of theatomizer are closed, and only that half of the atomizer over which thefabric is passed is called into action. From th e air-supply tube E'textend toward the discharge-nozzles of the size-supply pipes inclinedair-pipes e, the nozzles of which are located in vclose proximity to thenozzles of the size-supply pipes, so that the suction exerted by theescaping air lifts the size from the size-supply cylinder E3 and forcesthe salnein finely-divided spray or vapors against the nap of the plush.The brush-rolls arealternately rotated in opposite directions and serveto work the size thoroughly into the nap, so as to incorporate it withthe fibers thereof.

Motion is imparted to the brush-rollsCaud beater-fran1e D from thepulleys of a drivingshaft S, which is supported in bearings at thecenter of the machine. A cross-belt passes from one of the pulleys onthe drivingshaft over pulleys at the ends of 'one-half of thebrush-rolls and over a pulley of the beater' frame, while a second beltpasses over the pulleys of the remaining brush-rolls, as shown in Fig.l. vlVhen the plush arrives at the opposite end of the machine, it ispassed below a guide-drum E of smoothly-polished steel. A gear-wheel mon the shaft of the guidedgum meshes with a pinion n on the shaft o,said shaft being provided with a pulley p, from which a crossed belt qextends to a pulley 9' on the driving-shaft S, these parts or theirequivalents constituting the means whereby motion is communicated to theguidealrum in the direction as shown by the arrows in Eig. l. From theguide-drum F the plush passes over a draft-roller G, which is mountedwith cards and located at the upper corner of the support-frame A, andwhich roller receives rotary motion by a crossbelt s from a pulley ofthe shaft o of the driving-pinion of the guide-drum E. From thedriving-roller G the plush passes over a number of intermediateguide-rollers g g to a second card-mounted draft-roller G at theopposite corner of the machine, and from the same over a smallerguide-rollerto a suitable folding device.

The shafts a andi: of the card-mounted rollers G G are provided withpulleys w and w', connected by a belt y, whereby motion is transmittedto roller G.

Below the guide-drum E is located the drying apparatus ll, which isshown in detail in Figs. 5 to 8. The drying apparatus consists of agas-heated cast-iron box 71 having a horizontal polished top surface,above whiehthe nap of the plush is guided by the drum 'E at such adistance that the nap does not touch the horizontal top surface oftheheating-box. A pipe 7L' extendslongitudinally through the heatingbox71, said pipe beingprovided at its upper part with a number of smalljet-holes 7L. Gas is supplied by gas-supply pipes 71,", provided withstopcocks at both ends and at. the middle part of the heating-box 71said gaspipes terminating in hollow spherical casings 7L, which areprovided at that part which surrounds the gas-supply pipes withair-inlet openings 7L, through which a certain quantity of air is drawnin and mixed with the gas, so that the gas and air mixture when emittedthrough the jet-openings 7b2 of the longitudinal pipe 7L burns with ablue heating-llame on the principle of the Bunsen burner. The additionalquantity of air required for the combustion of the gas and air mixtureis supplied through the open bottom of the heating-box 7L, while theproducts of combustion are conveyed to the outside through openings 7LGin the ends and side walls of the heatingbox 7L, which openings areshown respectively, in Figs. 5 and S. The heat radiated from the uppersurface of the heatingbox 71j dries the finely-distributed size that hasbeen incorporated into thcnap of the plush, so that a tine luster isimparted to the nap.

The drum E, under which the plush is passed, is supported in bearings inhorizontal arms F', which are pivoted upon the shaft o of thedrivingpinion n, and supported at their opposite ends onvertically-movable screw-rodsf, which engage threaded sleeves f of thearms E and rest loosely at their lower ends on fixed posts f2. The drumF is vertically adjusted by the screw-posts f, as shown in Fig. l, sothat the distance at which the fabric passes from the heating apparatuscan be readily adjusted, according to the degree of heat to which thefabric is to be exposed in its passage under the drum.

The machine is provided with means for raising the drum bodily on theapproach of a seam in the fabric, consisting of an elbow-lever F2,pivoted in a bearing f3 of the frame. The lower short arm of said leveris provided with a recess in its inner face, in which is disposed aninwardly projecting anti friction roller f5. The trunnion f of theelbow-lever E2 may extend across the machine in the form of a rod and beprovided at its opposite end with a short arm corresponding with theshort arm of said lever F2. This short arm may also be provided with ananti-friction roller. The anti-friction rollers of the short arms 'roorest against the under sides of the support-` plush by contact with theheating-surface is prevented. y l

Each piece of plush is passed twice through the machine, t-he secondtime with its end reversed, so that the nap of the plush receives asplendid luster and finish.

By my improved finishing-machine large quantities of plush can befinished in a uniform, quick, and effective manner at a considerablesaving of time and labor, While a superior finish is imparted to thenap, as the operations of beating, sizing, and heating are performed inan automatic and reliable manner.

Having thus described my invention, I claim as newand desire to securebyLetters Patentl. The combination of draft and guiding rollers for thefabric, a rotary beater, an atomizing apparatus adjoining said beater, anumber of brush-rolls for incorporating the size into the nap of theplush, and a number of supporting rolls alternating with saidbrush-rolls, substantially as set forth.

2. The combination of a supporting-frame having draft and guidingrollers for the fabric, a rotary beater at one end of the machine, anatomizing apparatus adjoining said beater, a number of rotarybrush-rolls arranged below the fabric, a number of alternatingsupporting-rolls located above the fabric, a guidedrum at the oppositeend of the machine, andv a heating apparatus below the guide-drum,substantially as set forth.

3. The combination of a rotary beater, a number of brush-rolls, a numberof supporting-rolls alternating with the brush-rolls, and an atomizingapparatus located between the beater and brush-rolls and composed of ahorizontal size-supply cylinder having suction-pipes provided withdischarge-nozzles, and an air-supply pipe having inclined airdischargepipes Whose nozzles terminate above the nozzles of the size-supplypipes, substantially as set forth.

4. The combination, with a guide-drum, of a heating apparatus locatedbelow said drum, therheating apparatus being composed of a cast-metalheating-box provided with a longitudinal pipe having j et-openings, andgas and air mixers communicating with said pipe for supplying themixture of gas and air for heating the boX, substantially as set forth.

5. The combination of a supporting-frame having draft and guidingrollers for the fabric, a heating apparatus, pivoted arms, a guide-drumsupported in said arms above the heating apparatus, and a fulcrumedelbowlever adapted to engage said arms for lifting the drum.

6. The combination, with a supportingframehaving draft and guidingrollers for the fabric, of a heating apparatus, al guidedrum above theheating apparatus, and means for vertically adjusting said drum,substantially as set forth.

In testimony that l claim the foregoing as my invention I have signed myname 1n presence of two subscribing witnesses.-
